Just a human being cannot function without a brain, such a computer cannot function without a central processing unit. It is a brain that guides the human body to function. Without a central processing unit, your system is like a abnormal human being. The central processing unit operates on the same principle. Now let’s take a look at how the central processing unit works.
- Computer Architecture
Instruction set architectures Caching Pipelines Hyperthreading
Instruction set architectures
This word guesses what his job will be, looking at it from the figure.
The computer never understands English Directly. The Computer language is 0 and 1 which means ON and OFF. Instruction set also known as ISA. The instruction set depends on these things.
Registers Memory architecture Interrupt Exception handling External I/O Addressing modes Instructions
Examples of instruction set
ADD COMPARE IN JUMP JUMP IF LOAD OUT STORE
It temporarily saves data. It is capable of processing very high speed data. This makes your data very effective.
Examples of hardware caches
CPU cache GPU cache (Graphics processing units) DSPs (Digital signal processors)
In computing, this is also known as data pipeline. This allows data to be stored and run. This is a technique in which many tasks can be performed at the same time. Pipeline enhances the ability to work.
Types of Pipeline
Arithmetic Pipeline Instruction Pipeline Arithmetic Pipeline
This operation is very useful for floating points like X = R*2^b and Y = K*2^a. It now operate in four stages.
Compare the exponents of Computing. Align the Computing. Add or subtract Computing Produce the result of Computing
- CPU Design Process
This design is accomplished in the following points.
Schematics Transistors Logic gates Clocking
Logic gates are building blocks of any digital system. Logic gate plays a very important role. Now we look at their types.
AND Gate OR Gate NOT Gate NAND Gate NOR Gate XOR Gate XNOR Gate Half Adder Full Adder N-Bit Parallel Adder N-Bit Parallel Subtractor Half Subtractors Full Subtractors Multiplexers Demultiplexers Decoder Encoder
These are the building blocks of the integrated system. They are numbered in the million in the modern central processing unit. A transistor in PC processors regularly signals on or off. Be that since it could, transistors will in like manner alteration the level of a la mode being sent. For instance, a keyboard could join an advancement of transistors which might be utilized to frame bigger the sign stream. The broadened sign makes AN exceptional data yield. In lightweight of their base attempt and high reliableness, transistors have generally recorded vacuum tubes for data escalation capacities
There are two types of transistors on a modern CPU
The clock is similar to the original clock, but its working style is different. CPU can perform per second. It has to do with system speed and this speed is also called clock rate. Clock speeds are expressed in megahertz (MHz) or gigahertz (GHz). Intel 80286 microprocessor requires 20 cycles to multiply two numbers. Expansion buses also have clock speeds.
